I don't mind the changes to THM so much (I use my little Lalafell for magic-y leveling), but I would hope they would increase Conjurer's AoE range if we are to use them as the main healers now. The only reason I preferred healing on THM was the fact that CON's range is atrocious.
If they address that whenever this more mage-centric update they speak of comes, then I will be happy. If they never do, I will not.
I will withhold judgment on the MP costs and whatnot until I get back in game and get a chance to run around on my Lalafell, but right now, I am a bit concerned. Mostly I play as a duo though so it shouldn't be so bad.
